CUT-Ulli? FR GltAlEN-SPOUTS.

Specification of Letters Patent.

Patented Nov. 5, lilith.

Application filed July 14, 1917. Serial No. M0587.

. U T o all whom it may concern Be it known that l, CLAUDE SIMMONS, a citizen of the United States, and a resident of Gibson City, in the county of Ford and State of lllinois, have invented a certain new and useful improvement in Cut-@ifs for Grain-Spouts, of which. the following is a specification.

The present invention relates to grain spouts and the like, and more particularly to an improved cut-oli' for controlling the flow of grain therethrough. u

An object of the present invention is to provide a simply and economically constructed spout and .cut-olf therefor which may be manually controlled from a point below the spout, and which is adapted particularly for controlling the flow of small grain without waste.

Another object of the present invention l is to provide a spout and cut-od which may be entirely made from sheet metal of the desired thickness, and which may be galvanized `to render the same durable and lasting. y u

The `above and other `objects and advantages of this invention will be in part described, and in part understood, from the,

following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:

`Figure 1 is a front elevation of a portion of a crib having a grainlspout and cut-od contructed according to the present invention applied thereto.

Fig. 2 is a longitudinal section through the same taken transversely through the cut-off.

F ig. 3 is a similar view taken longitudinally through the cut-off, and showing a slight modification of the same.

Fig. l is a detail perspective view of the valve employed. l y

Fig. 5 is a detail perspectiveview of the pulley supporting member shown in Fig. 3.

Referring to this drawing, A designates a suitable support, which may be a crib or the like containing a bin in the usual manner and to which the spout of this invention may be connected.

'llhe spout comprises an upper hopper section l0 of preferably frusto-conical form, and which tapers downwardly, the section 1() being provided at its upper end with an attaching flange 11 secured by screws or the like to the support A. The lower end of the hopper section 10 is provided with a depending neck 12 of any desired length, and which is provided upon its lower extremity with an outturned annular flange 13. ."llie spout also provided with an outlet neck portion 1d of annular form having upon its upper end an outturned annular flange l5. Between the flanges 13 and 15 are clamped a pair of guideplates 16 and 1i' which may be of disk form, and which are provided with registering apertures 18 and 19therethrough. Clamping bolts 2O engage through the flanges 13 and l5, and the outer marginal edge portions of the guide plates 16 and 17 to hold the element in clamped position in the spout.

The intermediate portions of the plates 16 and 17, within the spout, are pressed upwardly and downwardly away from each other to provide therebetween a space adapt-- ed to receive a slide valve 21. The slide valve 21, as shown in detail in Fig. el, com prises an elongated metallic plate having an opening 22 intermediate the ends thereof adapted to register with the openings 18 and 19 in the guide plates 16 and 17 for the purpose of admitting the flow of grain or the like downwardly through the spout. lhe opposite ends of the valve plate 21 pro' ject beyond the sides of the spout and are preferably reduced in width to form tongues 23 which are rolled downwardly in overturned relation to provide eyes 24 through which may be secured the inner adjacent ends of flexible cords or cables 25.` rllhe eyes 24: also form stops for limiting the sliding movement of the plate 21 when shifted into opposite positions, as shown in Fig. 1, the'eyes 24 engaging against the opposite side portions of the lower guiding plate 17.

When the spout and cut-olf is mounted in' the frame of a doorway or the like, as shown in Fig. 2, pulleys 26 are mounted in brackets 27 which are secured against the inner opposite sides of the vertical portions of the framework. 'llhe cables 25 pass over the pulleys 26 and downwardly against the op posite sides of the frame A, and are provided upon their lower ends with suitable handles 28 which may be grasped one at a time for shifting the valve 21.

T he modication disclosed in llig. 5 shows the upper guide plate 16a having at opposite sides integral relatively thin arms 2l'a which project laterally beyond the opposite lill 'lll

Ell

sides of the spout. The outer ends of the arms 27a are turned downwardly, and are bifurcated for the passage of the cables 25 therethrough. The lower ends of the arms 27al are overturned to form eyes 29 adapted to receive transverse pins 30 therethrough upon which the pulleys 26a are mounted, the latter being arranged between the fork arms on the extremities of the bracket arms 27a.

The bracket arms 27a are employed when the spout is arranged against the outer side of a crib or the like and where no lateral supports are found.

In both forms of the invention, the operation is identical, for when it is desired to adjust the valve 2l it is only necessary to grasp one of the handles 28 and draw the cable 25 connected thereto downwardly. IIhis operation shifts the valve 2l between the guide plates 16 and 17 and moves the opening 22 into and out of register with the openings 1S and 19 in the guide plates.

The entire device may be constructed from sheet metal, and is relatively strong and durable, and is economical in its distribution of grain. The device also occupies but relatively small space and may be modified in? construction and design for attachment to bins of vvarious forms.

I claim l. In a grain spout, the combination, of a hopper section, an outlet section, guiding Iplates positioned between the adjacent ends of the hopper and outlet sections and having registering openings therethrough, a slide valve arranged between said guide plates and provided with an opening adapt.

ed to register with the openings in the guide plates, the upper guide plate having at its opposite lateral edges outstanding arms with downturned forked extremities, rollers carried by the forked extremities, and flexible cables trained over the rollers and extending beneath the arms for engagement with the opposite ends of the slide valve to shift the saine.

2. In a grain spout, the combination of a hopper-section, an outlet section, a pair of guide plates positioned between the adjacent ends of the hopper and outlet section and having registering openings therethrough, the intermediate portions of said guide plates being offset from each other to provide a space therebetween, a slide valve slidably fitting between said guide plates and having an opening adapted to register with the opening in the guide plates, the end portions of said slidable valve being reduced in width and rolled to form eyes, said eyes adapted to engage against said guide plates to limit movement of the slide valve, the upper guide plate having at its opposite lateral edges outstanding arms, with downturned forked extremities, rollers carried in the forked extremities, and iiexible cables trained over said rollers and extending beneath the arms, said fiexible cables being connected to the rolled ends of said valve plate to shift the same.

3. In a grain spout, the combination of a hopper section, an outlet section, said hopper and outlet sections being provided with outturned lianges, a pair of guide plates arranged between the {ianges and the sections and provided with registering openings in axial alinement with the sections, said guide plates having their intermediate portions oliset in opposite directions to form a space therebetween, a metallic strip slidably lit.- ting in the space between the guide plates and having an opening therein adapted to vregister with the openings in the guide plates, one of said guide plates having laterally extending arms projecting beyond the opposite sides of the spout, rollers mounted in the outer ends of said arms, and flexible connectors trained over said rollers and having connection with the opposite ends of said slidable strip to shift the same in opposite direction and control the fiow of material through the spout.

et. In a grain spout, the combination of a hopper section, an outlet section, a pair of guide plates clamped between said sections and having registering openings therethrough, the intermediate portions of said guide plates being offset from each other to provide a space therebetween, an elongated plate slidably fitting between said guide plates and having an opening therethrough adapted to register with the openings in the guide plates, the upper guide plate having at its opposite lateral edges outstanding arms with down-turned forked extremities, rollers mounted in the forked extremities, and iiexible cables trained over the rollers and extending beneath the arms for engagement with the opposite ends of the elongated plate to shift the same.
